Tattoos, perhaps one of the oldest forms of communication or body art, have had and still have different meanings.
From healing powers to the identification of criminals, through myths and different beliefs or simply as a form of identification and affirmation of group belonging, tattoos are one of the most characteristic means of expression associated with sailors, soldiers, organized crime, gangs or urban tribes, as well as being a form of body adornment and expression of a lifestyle, philosophy or many people's beliefs.
